Hello:

Have an aero utility type question, but apparently the WUN Club only seems
to have a list server for posting loggings, etc., but not for basic
questions, so will try here.

Re all these "Huntress" frequencies that one sees:

Exactly what are they ?

Are they all Norad related, or also for general USAF usage, or... ?

Which are the most popular/used in the northeastern U.S. ?

Thanks,
Bob
